Styrene-Butadiene rubber (SBR)

Styrene-Butadiene rubber (SBR)

Styrene-butadiene or styrene-butadiene rubber (SBR) describe families of synthetic rubbers derived from styrene and butadiene (the version developed by Goodyear is called Neolite). These materials have good abrasion resistance and good aging stability when protected by additives. In 2012, more than 5.4 million tonnes of SBR were processed worldwide. About 50% of car tires are made from various types of SBR.

The styrene/butadiene ratio influences the properties of the polymer: with high styrene content, the rubbers are harder and less rubbery. SBR is not to be confused with a thermoplastic elastomer made from the same monomers, styrene-butadiene block copolymer.

Styrene-Butadiene rubber (SBR-1500)

1)Description:

Styrene-Butadiene rubber (SBR)–1500 is a high molecular weight Styrene butadiene rubber combining good extrusion behavior and superior compound properties.It has relatively wide molecular weight distribution and the butadiene component has an average about 9% Cis-1,4 , 54.5% trans and 13% 1,2 vinyle structure. SBR 1500 contains antioxidant to avoid product degradation.The high strength and great toughness of rubber permit the use of its elastic qualities.The properties of rubber show excellent resistance to cutting,tearing and abrasion.It has a relatively long,useful life under a wide variety of conduction.

2) Applications:

SBR-1500 is well suited for wide range of applications due to its unique properties.Some examples are :Tires,tread rubber and molded and extruded mechanical goods.

Styrene-Butadiene rubber (SBR-1502)

1)Description:

Styrene-Butadiene rubber (SBR)–1502 is a cold, 23.5% styrene SBR polymer made with a mixed–acid emulsifier, a non-staining stabilizer and a salt–acid coagulation. Provided that the compounds are formulated and processed correctly, the vulcanizates have very good abrasion , good heat and aging resistance, good mechanical properties , good electrical properties and good resistance to polar solvents and dilute acids.

2) Applications:

End uses include white sidewall tyres, foot wear, light and dark coloured mechanical goods and miscellaneous items where excellent physical properties and minimum discoloration and staining are required.

Styrene-Butadiene rubber (SBR-1712)

1)Description:

Styrene-Butadiene rubber (SBR)–1712 is staining type cold SBR ,extended with 27.5 part of highly aromatic oil. Provided that the compounds are formulated and processed correctly ,the vulcanized SBR–1712 has very good abrasion ,good electrical properties and good resistance to polar solvents and dilute acids.

2) Applications:

The SBR-1712 used for the production of tires, high quality technical rubber goods,moulded and extruded mechanical rubber goods and other industrial products where colour and staining are not decisive factors.
